application inea July 1i, ieee. serieu up. 725,469.

This invention relates to hulling machines, particularly/to that type adapted'jfor use in 1 hulling beansand the like, and Vhas tor its ol. ,ect the provision ojt a novel machine for this purpose so constructedand arranged as to break open the pods for extracting the beans, and efiectually shaking the Ventire niass to etect separat-ion of the beans so that they nia-y be collected in a suitable receptacit.. Y

ein important object is the provision ot a device oi this character in which the shaker n'iecl'rcnisrn is of peculiar construction and rrangel that it may have a inuch greater ee ot' inoveinent than is ordinarily the case Without danger ot disassociation ot thc L l v hl additionalobject is the provision ot a liulling niachine which will be extremely simple and inexpensive ,to manufacture, positive in action, efficient and durable in service, and a general viinproy/*lenient in the art.

With the above and otherr objects and 2rd-,

vantages in vievvythe invention consists in the combination and arrangement of parts to be hereinafter more ully described` and claimed and illustrated in the accompanying drawings in which.:V

l? terrine; more particu arly to the drawings, the numerati() designates generally a suitable supper-'ting trarne consisting of any necessary number ci longitudinal and trans'.- relse bars,7 legs or other' elements. Located at thetop ot one end of this/trame is a feed tablel ll which leads to three concaves l2, and 14h arranged in series. 'Ehe concave 12 is formed with tivo.v series ofY blades or knives livliich have their torwardedges 16 inclined and sharpened. Ilhe concaves 13 1 Drei/*Med with .rows otteeth or line 7 7 of Mounted above the respective concaves 12,V land lli are drums 18, 19 and 20, the for# nierotl which carries Slanting teeth 2l having sharp'edges 22 and the latter two of which carry teeth 23 cooperatingy with the teeth l?.V y this construction a beater is unnecessary and the blades or teeth 2l cooperating with the teeth or blades l5 Will act to cut up long Weeds which are generally J oundv mixed with the vines, this feature eliminating the trouble caused byivinding of? the Weeds upon and consequent clogging ot the cylinders or drums and their concaves.

'ihe druins 18, 19, and 20are carried by `shafts 211- 25 and 25, respectively equipped is applied vto the pulley 29 forl driving the` entire mechanism including that already described and that yet to be described.

At the opposite end ot" the machine is a transverse bar or other supporting nieinber 3l to which are connected resilient, preterably leather, straps 32 connected with the rear ends of elongated shaker bars 33 having upstanding ratchet-like projections or teeth 34 thereon to devne a riddle structure. .lournaledl through the traine is a shaft 35 having a plurality of crank portions 36 engaging through the forward ends of the respect-ive shaker or riddlel bars 23 forixnparting the requisite inoveinent thereto. This sha/,tt carries a pulley ltiounted at the loivcr portion ot the rear or second mentioned end ot the trarneL is a. collecting hopper 38 having a laterally e2;- tenuingdischarge chute 39 at its lower end, which chute has its bottoni tornied as a Wire screen 40- o r other foralninous material to perinit the'dropping out oit' sand and other small particles of'a heavy nature. This hopper is carried by hangers ll pivoted at 42ml the traine, and Withinthe upper portion ot the hopper is a screen ltbeloiv which is a. second screen 44, the t'ornier being of pivoted at lo and carrying a shaft t6 movable within slots ti in the frame and carrying a pulley t8. rl`he levers carry latches 45 cooperating with notched segn'ie-nts 45'. This shaft is formed with crank portions t9 engaged by pitmen 50 which extend forwardly and which are pivotallyconnected at l with the forward hangers Lll. rthe shaft 46 is formed with other cranks engaged within bearings 53 on a kicker frame 5t having its forward end carrying a link 55 connected at 56 with a hanger 5i which is in turn pivoted at on the underside of the table ll. The kicker frame carries a plurality of depending teeth 59 which are adapted to engage any accumulation vof matter on the screen t3 for moving the same to the rear end of the machine and discharging it onto the ground or floor.

Journaled across the hopper are shafts GO and 6l carrying rollers about which are trained carrier belts 63 which more in the direction of the arrow-and which are equipped with transverse cleats (3l moving rearwardly above the screen All for discharging any accumulation thereon. The shaft- 61 carries a pulley Mounted beneath the forward end of the machine is a blower casing GS within which a blower fan GT of conventional construction is mounted upon a shaft 58 carrying a pulley G9. rlhe blower casing has its discharge TO located below and somewhat in advance of the screens ht3 and l for blowing dust and dirt out of the beans or the like as they pass through the screens.

For driving the mechanism, provide a belt 7l engaging the pulley (it), extending over the pulley 30, under the pulley 3T, over the pulley a8, and under the pulley 65. By this peculiar arrangement it will be seen that all the mechanism is driven by means of this one belt, which in turn derives its power from the gears 2T and 29 rotated by the application of power to the pulley 29. 'tightening of the drive belt is effected by adjusting the levers 45.

ln the operation it is apparent that the bean plants are fed onto the table ll, from which they will be drawn so as to pass between the drums 18, 19 and 20 and their concaves 1Q, 13 and ll. The teeth 2l and l5 act to cut long vines and weeds and the teeth 1T and 23 operate to tear open the pods and to tear the pods from the'vines or plants. The entire mass of broken up matter is discharged from the rear end of the concave lstonto the shaker bars 33, the inclined teeth 3st ot' which will eventually move the vines rearwardly so as to discharee them at the rear end of the machine. The beans and fragments of stems, pods, and the like will drop down between the bars 33 onto the upper screen 43, the beans and small particles passing through this screen and onto the screen it The weeds, rines and other undesired matter which accumulates upon the screen -l-B are moved rearwardly by the kicker frame s: and are dif-charged at the rear end of the machine. it all times, there is a strong air blast from the blower which assists in the discharge of the chatix and which removes the dust from the beans as they fall. The screen lll, being of smaller mesh than the screen 43, positively prevents any chaff and debris from passing through so that only clean beans and possibly a little sand will pass into the hopper 3S. Sand and such matter 'falls out through the screen bottom l() of the discharge chute so that only clean beans pass to whatever receptacle is provided at the outlet end of the chute.

llfhile l have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

l claim:

l. In a machine of the character described, a supporting frame having closed sides, a horizontally arranged movable frame including longitudinal members and transverse members, a hanger pivotally mounted on the stationary frame, a connection between said hanger and said movable frame, the closed sides of the stationary frame having arcuate slots therein, bearings on the longitudinal members of said movable frame, a shaft having an intermediate c'ank portion engaged through said bearings and having other portions movably mounted along said arcuate slots: and a lever mounted exterior-ly of the stationary frame and having` a link connection with said shaft for 'ai-ying the position thereof, and means for rotating said shaft.

2.111 a machine of the character described, a stationary frame having closed sides, a horizontally arranged longitudinally movable frame suspended within said stiationary frame and including longitudinal members and transverse elements of toothlike formation. a shaft extending transrersely of said movable frame and provided with crank portions. bearing on the longitudinal members of said movable frame receiring said shaft. the closed .sides ot' the stationary frame having arcuate slots through which the shaft extends. a drive element on said shaft for ell'ecting rotation thereof, and a lever connected with, said shaft for varying the position thereof.
